HEAD Sonic Pro™ 200M Tennis Strings Reel , Black

The HEAD Sonic Pro™ 200M Tennis String Reel (Black) is a classic, highly popular soft co-polyester string designed for players who want the control, spin, and durability of a poly without the harsh, stiff feel typically associated with standard monofilaments.

HEAD Sonic Pro™ is engineered using a unique molecular structure made from soft co-polymer polyester combined with specialized lubricant additives.

Unlike traditional stiff polyesters (which can be harsh on joints), Sonic Pro is tuned specifically for comfort, touch, and lively rebound. The smooth profile combined with low-friction additives allows for slick string movement and rapid snap-back for easy spin generation. The Black colorway delivers a sleek aesthetic and offers a slightly crisper response compared to the original White or Orange versions.

Performance Profile

1. Comfort & Arm Friendliness: 8 / 10: Remarkably forgiving for a co-poly string. It absorbs shock effectively and ranks among the softer options in the poly category.
2. Control: 8 / 10: Excellent directional accuracy. It allows aggressive players to swing out while keeping the ball inside the lines.
3. Spin Potential: 7.5 / 10: While round (not shaped or rough), its slick coating promotes great main-string "snap-back" for easy topspin and slice depth.
4. Power: 7 / 10: Noticeably livelier and springier than stiff traditional polys (like Luxilon 4G or Solinco Tour Bite), providing nice ball acceleration.
5. Durability & Tension Maintenance: 6.5 / 10: Strong resistance to shearing and breaking, though like most soft co-polys, it will gradually lose its initial playability tension over time.

Best Suited For

1. Players Transitioning to Polyester: Ideal for intermediate to advanced players making their first move from multifilament/nylon to a poly string bed.
2. Arm-Conscious Poly Users: Great for players who love polyester performance but experience minor wrist or elbow discomfort from stiffer strings.
3. Big Swingers Needing Extra Comfort: Aggressive hitters looking for controllable pop, low vibration, and smooth spin capability.
4. Hybrid Setups: Excellent choice as a durable main string paired with a soft multifilament cross, or as a soft poly cross paired with a natural gut/multi main.
